Answer 1

Celiac disease is an autoimmune disorder where the body's immune system attacks the small intestine due to a reaction to gluten. This damages the microvilli and hinders nutrient absorption, leading to various symptoms.

Step-by-step explanation:

Celiac disease is an autoimmune disorder in which the body's immune system attacks its own tissues. It is caused by a reaction to proteins called gluten, which are found in wheat, barley, rye, and some other grains. The immune response damages the microvilli in the small intestine, leading to a reduction in the depth of the mucosa and hindering nutrient absorption. This can cause symptoms such as weight loss, anemia, diarrhea, and abdominal pain.
